Spencer knew just about everything. Science facts, grammar rules, math equations. But he couldn't seem to understand women.

It all started when you joined the BAU. No science or math seemed to have an answer to why his heart skipped out of his chest when you'd meet his eyes or the way his body was full of goosebumps when you'd pat his back.

Then, he subconsciously began to try and impress you. He only realized it when he basically jumped at the idea of carrying heavy boxes of files. A sane Spencer would never cheer at having to do something physical.

And suddenly, he was researching what women liked. Because if there was something he was good at, it was research.

'It's all biology. Women like dangerous men. Women love a threatening man. It's in their genes. Passed down from our ancestors. So, our advice? Be a threat.'

He wasn't so sure about it. It was an article on the internet. Surely not from a reliable source, and Spencer hated getting any information from the internet. But he could be dangerous, right? Easy peasy.
